Where The Hell Are The Hamsters?!

Ahhhhhh!!! We got home today at like 12am after like 4 hours of being out. And we get to thehamsters cage and guess what... THEY'RE GONE!!! The cage doesnt have a roof, but the walls are pretty high.. we've been using it for like 2 days and it hasnt been a problem before, but now they're not even there! We looked around the whole first floor! Cuz they're to small to go up the stairs.. and we didnt find anything!! THIS SUCKS!!! The only one home was the maid.. so shez gotta answer a few questions! We know she was with them since she left 2 small pieces of banana in the cage... yeah i know hamsters dont eat bananas.. tell that to her lol... but we didnt ask her yet cuz shez sleeping! I'll keep ya updated! Wish me luck!
